CHURN.

SPECIFICATION formingpart of Letters Patent No. 233,786, dated October 26, 1880.

Application filed August 14, 1880. (ModeL) To all whom it may concern:

Be it known that 1, JOHN MOOLURE, of Greenleaf, in the county of DeKalb and State of Missouri, have invented a new and valuable Improvement in Ghurns; and I do hereby declare that the following is a full, clear, and exact description of the construction and the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is arepresentation of a perspective View of this invention. Fig. 2 is a plan view of the same. Fig. 3 is a vertical central section, and Figs. 4 and 5 are detail perspective views.

This invention has relation to reciprocating churns; and it consists mainly in the construction and novel arrangement of the parallelmoving dasher having downward flanges at each end, the dash-rod pivoted to the dasher at its lower end and also to the cover, and the parallel connecting rod also pivoted to the dasher and cover; also, in the combination, with the above devices, of the intermediate perforated partition and of the crank-power adapted to give a vibratory movement to the dashrod, which is converted into a parallel reciprocating motion in the dasher, all as hereinafter fully shown and described.

In the accompanying drawings, the letter A designates the frame-work of the power devices, consisting of the parallel sills a, connected by crossbars b, the uprights c, horizontal side bars, d, and oblique bars 6, sustaining a driving gear-wheel, f, pinion g, and crankshaft h, having a pitman, k, running to the vibratory dash-rod B.

0 indicates the churn case or bucket, made usually in trapezoidal form, the sides being parallel and the ends y inclined toward each other, as shown in the drawings. This case is seated in the frame on the inside ledges of the rabbeted cross-bars b, and is removable from said frame, being held therein by a key, 1, pass ing through the side bars.

The churn-case is provided with bea'rin gs m, centrally, at the upper edge of each side wall, for the journals j of the rock-shaft D, through which the dash-rod passes, being secured in its slot by the rod n, which passes through the rock-shaft, or by means of a pin.

The cover E of the churn-case is seated between the upper edges of the side walls, its ends being rabbeted to engage the upper edges of the oblique end walls of the case, as shown in the drawings. In this manner it is firmly abutted at each end, so that it cannot move when placed in position. This cover is cut away between its sides at one end, the opening 1) extending beyond the central portion, and being bounded by the side arms, q, of the cover, which are grooved on their inner sides to form ways for the slide-cover F. The rockshaft D is pivoted between these cover-arms g at the central portion, and the slide-cover having been pushed in place between the arms, the cover is complete.

The dash-rod 13 extends downward within the churn to the dasher G, which consists of a horizontal body piece or board, H, having end tenons, r, and a central elongated slot, 8, and end flanges, K, which are mortised to receive the tenons ot' the board H, and which extend downward from said board on each side of the partition-board L, which is seated centrally and vertically in the lower part of the churn-case in guideways t, formed by means of strips attached to the side walls of the case. The lower end of the dash-rod is pivoted, by means of a pin, 1), in the slot of the dash, and a second connecting-rod, B, extending parallel with the dash-rod, between the cover and the dasher, is also pivoted, byits upper end, in a recess, w, of the cover, and by its lower end in the slot 8 of the dasher, pins 1" being used for this purpose.

The flanges Kof the dasher are usually perforated, as indicated at 2, similar perforations being made through the partition-board L, these perforations serving to subdivide the currents of cream, and to facilitate the breaking up of the butter-capsules.

The dasher of this churn moves in a reciprocating manner parallel with the bottom of 5 kept in the bottom of the churn to a great extent, and is not thrown upward, except by reaction.

I am well aware thatehurns havinginelined overhanging walls are common, and that it is not new to provide a reciprocating dasher or a partition-board with perforations.

What I claim, and desire to secure by Letters Patent, is

1. The combination, with the churn-cover E and the dash-rod B, pivoted thereto, of the downwardly-flanged dasher G, pivoted to the lower end of the dash-rod, and the connectingrod B, parallel to the dashrod, and also pivoted to the cover and dasher, whereby the dasher is moved parallel with the cover, substantially as specified.

2. In a churn having the vibratory dash-rod B, the combination, with said dash-rod, a parallel connecting-rod, B, and a parallel-moving downwardly-flanged dasher pivoted to these rods, of the overhanging inclined end walls, y,
